Abstract:

Attempts to apply Bradford's law of scattering and Lotka's law of productivity to bio-energy literature and to verify if the law holds good for ten abstracting services (eight international and two Indian). It has been verified that literature related to bio energy conforms to Bradford's law of scattering and that grouping of services (all services together) also yields a Bradford distribution. The new model developed in this study fits the data very satisfactorily - r value ranged from 0.952 to 0.998 (for papers from conference proceedings). The value of p (multiplication factor) for bio-energy literature ranged from 2.19 to 4.09 (except for IEA and ISA) for articles from journal titles and from 2.02 to 4.59 for papers from conference titles. Results of linear regression showed that Lotka's distribution holds good for bio-energy literature and the value of n ranged between 2.5 and 4.5. The K-S test confirmed these findings.
